Given Red : Blue : Green : Yellow = 6:5:2:2

1) Red - Green = 2, so ratio is 6:5 for 15 litres, so for 2 litres difference it has to be 30 litres.
Sufficient , A or D
2) Total is 30 litres in the ratio of 6:5:2:2
Sufficient . Hence D

Let the number of liters of red ink be = 6*x
blue ink be = 5*x
green ink be = 2*x
yellow ink be = 2*x
Statement 1 says , 6*x - 5*x = 2
x = 2
So the number of liters of green ink = 2 *2 = 4 liters

Statement 2 says , 15 *x = 30
x = 2
So the number of liters of green ink = 2 *2 = 4 liters

Each statement is sufficient.
Option D is the answer.

Please give me KUDOs if you liked my explanation.

But the stem doesnot specify the number of liters of the "certain batch of X" how can we say 4 liters in correct in Statement 1?

(1) The red ink is 2 more liters than the blue ink. Since the ratio of red:blue is 6:5 we can conclude that 12 liters of red was used.

Since the ratio of red:green is 6:2, we can then conclude 4 liters of green was used.

SUFFICIENT.

(2) Since we're given the ratio 6:5:2:2, and the total is 30 liters of color X, we can conclude 4 liters of green was used.

SUFFICIENT.

Answer is D.
